The mum-of-two, 25, was spotted at least a dozen times in the run up to her death at a clinic close to her mansion in Kent, wearing a hoodie so no one would recognise her.

The source – who met her at the Maidstone centre – said her husband Tom Cohen was unaware she was being prescribed the heroin substitute methadone.

He told The Sun: "We were on first name terms but I called her ‘P’.

"The last time I saw her she was fine, but furtive."

The source went on to describe how he recognised Peaches at the centre and she asked him not to say "anything to anybody".

He said: "She said she didn’t want her family or her husband to know about the drugs and it was top secret. She used to arrive on her own."

He added: “She was most concerned about her husband. She said, ‘You won’t believe it he’s a really straight family man. I married a really straight really nice bloke. He won’t understand, it would affect my kids’.

“She seemed like a really normal girl. To me she was a celebrity.”

The source said Peaches would likely have been prescribed about 20mg/ml of methadone which was a normal amount.

Yesterday it was revealed that heroin was "likely" to have played a part in Peaches' death, a saddening echo of her mum Paula Yates who died of an overdose in 2000.

The model was found by her 23-year-old husband slumped over a bed with one leg dangling down to the floor.

Police are now urgently looking for the dealer who supplied the tragic star with her fatal stash.

They are also trying to establish why no drugs or drug paraphernalia were found at the scene of her death.

During a five minute hearing in Kent, coroner Roger Hatch listened to brief details about the lead up to Peaches' death.

DCI Paul Fotheringham, of Kent Police, told the inquest: “A post mortem was carried out by a forensic pathologist and the initial results were inconclusive.

"Forensic samples were obtained and the results concluded the recent use of heroin and that the levels identified were likely to have played a role in her death.”

Peaches was alone in her house the weekend of her death.

Rock vocalist Tom had taken their two sons to stay with his parents in south-east London on Thursday April 3.

Friends became increasingly concerned as she flooded her Twitter account with photos of her kids.

Just hours before her death, Peaches uploaded a photo her herself as a young girl with her mum Paula, who died aged 41.
